Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic processing, concretely relates to a die closing mechanism, bottle blowing machine and injection molding machine. BACKGROUND

[0002] The existing die closing mechanism is used in the field of plastic processing, forms a die cavity sealed from the outside through closing, and then processes the raw material. The die closing mechanism comprises a support, a die plate assembly and a die assembly, the die plate assembly comprises a fixed plate, a movable die plate and a fixed die plate, the die assembly comprises two dies arranged on the opposite faces of the movable die plate and the fixed die plate, the movable die plate can reciprocate between the fixed plate and the fixed die plate, and when the movable die plate runs towards the fixed die plate, the dies approach each other and form a die cavity. In order to improve the motion precision of the die plate, the die closing mechanism comprises a pull rod arranged between the corresponding edges of the fixed plate and the fixed die plate and a driving member arranged on the fixed plate, one end of the pull rod is fixedly connected with the fixed plate, the other end penetrates through the movable die plate and is fixedly connected with the fixed die plate, the pull rod is cylindrical and has four rods, the pull rods are arranged between the corresponding corners of the fixed plate and the fixed die plate, the driving member is used for driving the movable die plate to reciprocate, the four corners of the movable die plate slide along the corresponding pull rods, so that the movable die plate and the fixed die plate are always in a parallel posture, thereby ensuring that the two are matched and fitted to enclose the die cavity. The die closing mechanism of this structure has the following defects:

[0003] Firstly, the die assembly of the die closing mechanism needs to be replaced according to production requirements, since the pull rods are arranged between the corresponding corners of the movable die plate and the fixed die plate, the distance between the two vertically arranged pull rods on the same side of the die plate assembly is small, which makes the die assembly unable to be disassembled horizontally, so the die assembly needs to be vertically hoisted and disassembled through the space between the two pull rods at the top of the die plate assembly, which not only requires a high space above, but also increases the difficulty of disassembling the die assembly due to the small assembly gap between the die assembly and the adjacent pull rods, which easily causes the pull rods and the die assembly to be damaged by collision and impact, affecting the use experience.

[0004] Secondly, since the die needs to be disassembled through the space between the adjacent pull rods, the distance between the pull rods is increased, which in turn causes the fixed die plate, the movable die plate and the fixed plate to need to be increased in size to be firmly connected with the pull rods, which not only increases the amount of raw material, but also increases the weight of the die closing mechanism, which causes the die closing action to need to resist a large inertia, reducing the opening and closing frequency and the opening and closing precision. UTILITY MODEL CONTENTS

[0005] In order to solve the prior art, the utility model provides a kind of die mechanism, bottle blowing machine and injection molding machine, the operation side of template assembly is provided with the frame-shaped main plate frame, so that the corner on the operation side of template assembly is exposed and forms the transfer channel for mold assembly disassembly, both facilitate mold assembly disassembly, prevent the situation of knock damage occurs, also by omitting pull rod to reduce the size of template assembly, improve the opening and closing mold frequency and precision.

[0006] The utility model realizes by the following mode: a kind of die mechanism, including support, the template assembly being set in support and the mold assembly being set in template assembly, the template assembly reciprocating open and close in support and drive mold assembly and form die cavity, the support includes the main plate frame and vice plate frame being separately arranged on the operation side and hidden side of template assembly, the main plate frame is exposed to the outside in the shape of the frame, to form the transfer channel for mold assembly horizontal disassembly replacement on the operation side of the template assembly.The main plate frame and vice plate frame are separately arranged on the two sides of template assembly, and support and position the template assembly, the main plate frame is set to the frame exposed to the outside, the mold assembly is exposed to the outside through the opening of main plate frame, both can form transfer channel using opening, without being separated from template assembly by vertical lifting, facilitate mold assembly to be transferred and disassembled and replaced by being maintained through horizontally arranged transfer channel, reduce the difficulty of mold assembly disassembly, improve the convenience of disassembly, also by increasing the size of transfer channel to increase the assembly gap around mold assembly, prevent mold assembly from being damaged due to knock impact.In addition, the main plate frame and vice plate frame are both plate-shaped and are connected with the corresponding plate pieces in template assembly, compared with the original pull rod structure, both reduce the size of each plate piece in template assembly by omitting the perforation for pull rod insertion, thereby reducing the size of die mechanism, reducing production cost, also by increasing the contact area between main plate frame, vice plate frame and each corresponding plate piece in template assembly to improve the positioning effect, ensure that mold assembly can be accurately opened and closed.

[0007] As preferred, the main plate frame is an integral structure, including two pairs of limit parts and a cross part across the corresponding ends of limit parts, the template assembly can be relatively moved between the limit parts along the setting direction of cross part, to switch mold assembly between die closing state and die opening state.The main plate frame of integral structure has better structural strength, thereby effectively positioning the corresponding plate pieces in template assembly.One end of limit part is connected by cross part, the other end is suspended and convenient to form the transfer channel exposed to the outside, both ensure the relative position between limit parts fixed, thereby positioning and guiding the corresponding plate pieces in template assembly, also by setting the transfer channel exposed and unobstructed to disassemble and replace mold assembly, improve the convenience of use.

[0008] Preferably, the transfer channel is located between the limiting parts, and the transfer channel is arranged in a horizontal direction perpendicular to the bridging part, so that the mold assembly is fully exposed to the operating side through the transfer channel. A bridging part is provided between the bottom ends of the limiting parts, forming an open and unobstructed space between the middle and top of the limiting parts, utilizing this space to form a transfer channel that facilitates the horizontal movement of the mold assembly. Compared to the original mold closing mechanism, the mold assembly has an upper space above it and a side space on its operating side. Since the pull rod above the operating side of the mold assembly is eliminated, and the upper and side spaces are interconnected and unobstructed, it facilitates the horizontal transfer of the mold assembly through the transfer channel formed by the side space. Furthermore, by increasing the size of the unobstructed space, the assembly clearance between the mold assembly and the sub-plate frame and the main plate frame is increased, thereby reducing assembly difficulty and preventing damage from collisions. The mold assembly is fully exposed to the operating side through the transfer channel, ensuring that the size of the transfer channel meets the transfer requirements of the mold assembly.

[0009] Preferably, the bridging portion is horizontally positioned and bridging the bottom ends of the limiting portions. A hoisting channel is reserved above the transfer channel for the movement of the lifting device. The lifting device moves within the hoisting space and drives the mold assembly to move horizontally along the transfer channel. The mold closing mechanism is suitable for equipment that opens and closes the mold plate horizontally. The tool for transferring the mold assembly can be moved either through the transfer channel horizontally positioned with the mold assembly or through the hoisting channel positioned above the mold assembly and in the same direction as the transfer channel, providing multiple options for tools used to disassemble and move the mold assembly.

[0010] Preferably, the bridging portion is vertically arranged, and the mold assembly moves vertically between the limiting portions to allow the mold assembly to switch between vertical opening and closing. The limiting portions are vertically positioned at both ends of the bridging portion. The mold closing mechanism is suitable for equipment that allows the mold assembly to open and close vertically. The tool for transferring the mold assembly can be moved through a transfer channel that is horizontally arranged with the mold assembly, facilitating the disassembly of the mold assembly.

[0011] Preferably, the limiting part is set at the same height as the template assembly to increase the contact area between the limiting part and the corresponding plate in the template assembly. The corresponding surfaces of the limiting part are set parallel to each other, so that the corresponding plate on the template assembly can remain parallel to each other after it is attached to the limiting part, thus ensuring the precise opening and closing of the mold.

[0012] Preferably, the limiting part and the bridging part are connected by rounded corners, which effectively disperses the stress at the connection between the limiting part and the bridging part and protects the motherboard frame.

[0013] Preferably, the mold assembly includes a fixed plate, a movable mold plate, and a fixed mold plate. The fixed plate and the fixed mold plate are respectively attached to the corresponding sidewalls of the limiting portion. The fixed plate is provided with a driving member that drives the movable plate to move back and forth. The movable mold plate is driven back and forth along the direction of the bridging portion and cooperates with the fixed mold plate to drive the mold assembly to switch between a mold-closed state and a mold-open state. The movable mold plate moves back and forth along the length direction of the bridging portion so that the mold assembly can switch between a mold-closed state where the movable mold plate approaches the fixed mold plate and a mold-open state where the movable mold plate approaches the fixed plate. The fixed plate and the fixed mold plate are parallel to each other and are respectively fixed to the corresponding limiting portion. The mold assembly includes a first mold plate and a second mold plate disposed on the facing surfaces of the movable mold plate and the fixed mold plate, ensuring that the first mold plate and the second mold plate can switch between a mold-closed state where they are closed together and a mold-open state where they are separated.

[0014] Preferably, the template assembly includes two parallel fixed plates and two movable templates disposed between the fixed plates. The fixed plates are respectively attached to the corresponding sidewalls of the limiting portion. Each fixed plate is provided with a driving component that drives the corresponding movable plate to reciprocate. The movable templates mirror-move and drive the mold assembly to switch between a closed mold state and a closed mold state. The movable templates reciprocate along the length of the cross-joint, allowing the mold assembly to switch between a closed mold state where the movable templates face each other and a closed mold state where the movable templates separate. The fixed plates are parallel to each other and respectively fixed to the corresponding limiting portions. The mold assembly includes a first mold plate and a second mold plate disposed on the facing surfaces of the two movable templates, ensuring that the first mold plate and the second mold plate can switch between a closed mold state where they are closed together and a closed mold state where they are separated.

[0015] Preferably, a brake limiting component is provided between the fixed plate and the corresponding moving platen. The moving platen moves into position and is locked by the brake limiting component. When the mold assembly is switched and in the mold closing state, there is a high positioning accuracy requirement for the moving platen. By setting the brake limiting component, the posture of the moving platen is corrected and accurately positioned. This ensures that the moving platens maintain a parallel posture with each other or with the fixed platen through correction, and also ensures that the mold assembly forms the mold cavity through precise closing, preventing the mold cavity from deforming due to the force displacement of the moving platen.

[0016] Preferably, both the sub-plate holder and the main plate holder are U-shaped, and are symmetrically arranged on the operating side and concealed side of the template assembly. The sub-plate holder and the main plate holder have the same contour structure, which facilitates mass production and shared use, and also provides balanced positioning for the two sides of the plates within the template assembly. The main plate holder and the sub-plate holder are respectively arranged on the operating side and concealed side of the mold closing mechanism, ensuring that both sides of the mold closing mechanism have transfer channels for easy replacement of mold components, thus improving operational flexibility.

[0017] Preferably, the sub-plate frame includes two parallel crossbars, which are positioned at the top and bottom of the concealed side of the template assembly. The two ends of the crossbars are fastened to the edges of the corresponding plates, serving both to fix and position the plates, ensuring they remain parallel, and to effectively reduce the plate size. This eliminates the need for pre-drilling holes for the tie rods in the original structure, thereby reducing the volume of the mold-closing mechanism and lowering the production cost of the mold-closing mechanism.

[0018] Preferably, the sub-frame is rectangular and includes vertical bars positioned between the corresponding ends of the horizontal bars. The corresponding sidewalls of the vertical bars are all fitted and fixedly connected to the corresponding plates of the template assembly. The vertical bars are positioned between the corresponding ends of the horizontal bars, and their fit against the edges of the corresponding plates ensures that the horizontal bars remain parallel, thus positioning the top and bottom of the plates and ensuring their parallelism. They also limit the vertical bars, ensuring their parallelism and the parallelism of the plates, thereby guaranteeing the opening and closing accuracy of the mold assembly.

[0019] A blow molding machine includes a base, on which a heating mechanism, a transfer mechanism, a blow molding mechanism, and a mold closing mechanism are mounted. The transfer mechanism receives preforms from the heating mechanism and conveys them to the mold closing mechanism, so that the preforms are blown into bottles by the blow molding mechanism within the mold closing mechanism. The operating side of the mold closing mechanism has a transfer channel, facilitating user replacement of mold components according to processing requirements, thereby improving ease of use by reducing the difficulty of mold component replacement.

[0020] An injection molding machine includes a base, on which an injection molding mechanism and a mold clamping mechanism are mounted. Softened raw material in the injection molding mechanism is conveyed to a mold cavity within the mold clamping mechanism and cooled and solidified. The operating side of the mold clamping mechanism has a transfer channel, facilitating user replacement of mold components according to processing requirements, thereby improving ease of use by reducing the difficulty of mold component replacement.

[0021] The outstanding advantages of this invention are as follows: The main board frame and the sub-board frame are respectively placed on both sides of the template assembly, providing support and positioning for the template assembly. The main board frame is designed as an upward-facing exposed C-shape, with the mold assembly exposed outward through the opening of the main board frame. This opening forms a transfer channel, eliminating the need for vertical lifting to detach the mold assembly from the template assembly. It facilitates the transfer, disassembly, replacement, and maintenance of the mold assembly through the horizontally set transfer channel, reducing the difficulty of disassembly and assembly and improving convenience. Furthermore, by increasing the size of the transfer channel, the assembly clearance around the mold assembly is increased, preventing damage to the mold assembly due to impacts. In addition, both the main board frame and the sub-board frame are plate-shaped and fit snugly to the corresponding plates within the template assembly. Compared to the original tie rod through-hole structure, this design reduces the size of the plates within the template assembly by eliminating the through holes for the tie rods, thereby reducing the size of the mold closing mechanism and lowering production costs. It also improves the positioning effect by increasing the contact area between the main board frame, sub-board frame, and the corresponding plates within the template assembly, ensuring precise opening and closing of the mold assembly.

[0029] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] This embodiment provides a mold closing mechanism.

[0032] like Figure 1 The mold closing mechanism shown comprises a support, a template assembly 1 disposed within the support, and a mold assembly 2 disposed within the template assembly 1. The template assembly 1 reciprocates within the support, driving the mold assembly 2 to enclose and form a mold cavity. The support includes a main board frame 3 and a secondary board frame 4 disposed on the operating side and concealed side of the template assembly 1, respectively. The main board frame 3 is an upwardly exposed U-shape, forming a transfer channel 5 on the operating side of the template assembly 1 for horizontal disassembly and replacement of the mold assembly 2. The main board frame 3 and the secondary board frame 4 are placed on both sides of the template assembly 1, providing support and positioning for the template assembly 1. The main board frame 3 is set as an upward-facing exposed C-shape, and the mold assembly 2 is exposed outward through the opening of the main board frame 3. The opening can be used to form a transfer channel 5, eliminating the need for vertical lifting to remove it from the template assembly 1. This allows the mold assembly 2 to be easily transferred, disassembled, replaced, and maintained through the horizontally set transfer channel 5, reducing the difficulty of disassembly and assembly of the mold assembly 2 and improving the convenience of disassembly and assembly. Furthermore, by increasing the size of the transfer channel 5, the assembly clearance around the mold assembly 2 is increased, preventing damage to the mold assembly 2 due to bumps and impacts.

[0033] In this embodiment, the mold closing mechanism includes an operating side and a concealed side. The operator stands on the operating side to control the mold closing mechanism. The mold closing mechanism includes a main board frame 3 disposed on the operating side and a secondary board frame 4 disposed on the concealed side. The main board frame 3 and the secondary board frame 4 cooperate with each other to fix and position each plate in the template assembly 1, thereby ensuring that the mold assembly 2 installed on the template assembly 1 can accurately switch between the mold opening state and the mold closing state.

[0034] In this embodiment, the motherboard bracket 3 is an integral structure and is in the shape of an upwardly exposed U-shape. The motherboard bracket 3 includes two opposing and vertically arranged limiting parts 6 and a connecting part 7 (e.g., ...) that spans the bottom ends of the limiting parts 6. Figure 2 As shown, the area enclosed between the limiting parts 6 and above the bridging part 7 forms the transfer channel 5. The transfer channel 5 is located between the limiting parts 6 and is arranged in a horizontal direction perpendicular to the bridging part 7. The outer port of the transfer channel 5 faces the operator, and the inner port faces the mold assembly 2, ensuring that the mold assembly 2 can be horizontally transferred and disassembled through the transfer channel 5. Compared with the original mold closing mechanism, the pull rod located on the upper part of the operating side of the mold assembly 1 has been removed, making the upper space above the mold assembly 2 and the side space on the operating side interconnected and unobstructed. This ensures that the mold assembly 2 has a large assembly gap when passing through the transfer channel 5, which not only facilitates the mold to pass through the transfer space, but also provides room for the tools for disassembling and assembling the mold assembly 2, effectively reducing the difficulty of mold disassembly and assembly and improving ease of use.

[0035] In this embodiment, the template assembly 1 is a single-moving template 9 structure, including a fixed plate 8, a moving template 9, and a fixed template 10. The fixed plate 8 and the fixed template 10 are respectively attached to the corresponding side walls of the limiting part 6. The fixed plate 8 is provided with a driving member 11 that drives the moving plate to move back and forth. The moving template 9 is driven back and forth along the setting direction of the cross joint 7 and cooperates with the fixed template 10 to drive the mold assembly 2 to switch between the mold closing state and the mold opening state. The fixed plate 8 and the fixed template 10 are parallel to each other and are respectively attached to the corresponding surfaces of the limiting part 6. The moving template 9 can move back and forth between the fixed plate 8 and the fixed template 10 along the length direction of the cross joint 7. The mold assembly 2 includes a first mold and a second mold disposed on the corresponding surfaces of the moving template 9 and the fixed template 10. The moving template 9 achieves the switching of the mold assembly 2 between the mold closing state where the first mold and the second mold are closed and the mold opening state where the first mold and the second mold are separated by reciprocating movement. Since the middle section and the top section of the two limiting parts 6 are both open structures without any obstruction, and the distance between the limiting parts 6 is always greater than the distance between the moving template 9 and the fixed template 10, the mold assembly 2 is always completely exposed in the transfer channel 5 set between the limiting parts 6, ensuring that the transfer tool can contact the mold assembly 2 through the transfer channel 5 and transfer it horizontally outward, effectively improving the convenience of transfer.

[0036] In this embodiment, the limiting part 6 is set at the same height as the template assembly 1 to increase the contact area between the limiting part 6 and the corresponding plate in the template assembly 1. The bottom end of the limiting part 6 is flush with the bottom edge of the corresponding plate, and the top end is flush with the top edge of the corresponding plate. The sidewall of the limiting part 6 is flat and fits tightly against the corresponding plate, effectively improving the reliability of limiting the plate and thus ensuring that the fixed plate 8 and the fixed template 10 remain parallel.

[0037] In this embodiment, the limiting part 6 and the bridging part 7 are connected by rounded corners. The top of the limiting part 6 is subjected to the force from the corresponding plate and is transmitted downward to the end of the bridging part 7. By setting the rounded corners, the force accumulated between the limiting part 6 and the bridging part 7 is dispersed, which effectively improves the connection strength between the two and thus ensures that the relative position between the limiting parts 6 is fixed.

[0038] In this embodiment, a brake limiting component 12 is provided between the fixed plate 8 and the corresponding moving template 9. The moving template 9 moves into position and is locked by the brake limiting component 12. The brake limiting component 12 can lock and position the moving template 9 after it has moved into position, thereby ensuring that the relative position between the moving template 9 and the fixed plate 8 is fixed. Furthermore, the main plate frame 3 and the secondary plate frame 4 are used to ensure that the relative positions between the moving template 9, the fixed plate 8, and the fixed template 10 are fixed, ultimately ensuring that the relative positions between the first mold and the second mold are fixed, and ensuring that the mold cavity contour remains unchanged.

[0039] In this embodiment, the support includes a guide rail disposed below the template assembly 1. The guide rail is used to support the moving template 9 and to precisely guide the movement of the moving template 9, ensuring that the moving template 9 always remains parallel to the fixed template 10.

[0040] In this embodiment, the sub-plate frame 4 is square-shaped (e.g., ...). Figure 3 As shown, the template assembly 1 includes two parallel horizontal bars 13 and vertical bars 14 positioned between corresponding ends of the horizontal bars 13. The corresponding sidewalls of the vertical bars 14 are all fixedly connected to the corresponding plates of the template assembly 1. A secondary plate frame 4 is positioned on the concealed side of the template assembly 1. Two horizontal bars 13 are positioned between the top and bottom ends of the fixed plate 8 and the fixed template 10 on the concealed side, respectively, ensuring that the distance between the top and bottom ends of the fixed plate 8 and the fixed template 10 remains constant. This, in turn, cooperates with the main plate frame 3 to ensure that the fixed plate 8 and the fixed template 10 remain parallel. The upper horizontal bars 13 provide positioning for the tops of the fixed plate 8 and the fixed template 10, compensating for the lack of connection and limiting on the operating side of the top of the fixed plate 8 and the fixed template 10, ensuring that the structural strength of the template assembly 1 meets the usage requirements. The end side wall of the crossbar 13 is provided with a notch. The crossbar 13 is fastened to the edge of the corresponding plate through the notch, which not only ensures that the crossbar 13 is firmly connected to the plate, but also effectively reduces the size of the plate, thereby reducing the volume of the mold closing mechanism, facilitating processing, assembly and transportation, and improving ease of use.

[0041] In this embodiment, the vertical rod 14 spans between the corresponding ends of the horizontal rod 13, and the side wall of the vertical rod 14 is tightly fitted with the corresponding plate body, thereby increasing the contact area to improve the reliability of the limiting position.

[0042] In this embodiment, the transfer channel 5 is set at the same height as the mold assembly 2, facilitating the transfer of the mold assembly 2 by using forklifts, forks, or other tools to traverse the transfer channel 5 horizontally. Furthermore, a lifting channel is reserved above the transfer channel 5 for the movement of a lifting device. The lifting device moves within the lifting space and drives the mold assembly 2 to move horizontally along the transfer channel 5. The lifting device vertically supports the mold assembly 2, and the lifting device and mold assembly 2 are transferred horizontally through the lifting channel and transfer channel 5 respectively. This effectively reduces the height requirement above the mold closing mechanism and ensures that the mold assembly 2 can be transferred horizontally along the transfer channel 5, which should also be considered a specific implementation method of this embodiment.

[0043] Understandably, the sub-plate frame 4 includes two parallel horizontal bars 13, which are respectively placed on the top and bottom of the concealed side of the template assembly 1. The vertically placed horizontal bars 13 are used to position the fixed plate 8 and the fixed template 10, which should also be regarded as a specific implementation of this embodiment.

[0044] Understandably, the mold clamping mechanism can be used on vertical blow molding machines (such as...).Figure 4 As shown, the bridging portion 7 is vertically arranged, and the mold assembly 2 moves vertically between the limiting portions 6. By flipping the entire mold closing mechanism, the bridging portion 7 is vertically arranged, and the mold assembly 2 can be vertically opened and closed to meet usage requirements. It also provides a horizontally arranged transfer channel 5, which can be used for product transfer, improving the convenience of product transfer. This should also be considered a specific implementation of this embodiment. In addition, the template assembly 1 is a double-moving template 9 structure, including two parallel fixed plates 8 and two moving templates 9 arranged between the fixed plates 8. The fixed plates 8 are respectively attached to the corresponding side walls of the limiting portions 6. The fixed plates 8 are provided with driving members 11 that drive the corresponding moving plates to reciprocate. The moving templates 9 move in a mirror image and drive the mold assembly 2 to switch between the mold closing state and the mold opening state. By driving the two moving templates 9 with two sets of driving members 11, the moving templates 9 can move in a mirror image between the two fixed plates 8 and drive the mold assembly 2 to switch between the mold closing state and the mold opening state. This should also be considered a specific implementation of this embodiment.

[0045] Example 2:

[0046] Compared to Embodiment 1, this embodiment provides another mold closing mechanism.

[0047] like Figure 5 As shown, both the sub-plate frame 4 and the main plate frame 3 are U-shaped. They are symmetrically arranged on the operating side and concealed side of the template assembly 1, forming horizontally arranged transfer channels 5 on both sides. This allows operators to easily select the transfer channel 5 for disassembly and assembly of the mold assembly 2 as needed. The upper part of the template assembly 1 is an open structure. Compared to the original mold closing mechanism, the tie rods located on both sides of the top of the template assembly 1 are eliminated, increasing the open space to facilitate the disassembly and assembly of the mold assembly 2.

[0048] In this embodiment, the limiting parts 6 corresponding to the sub-plate frame 4 and the main plate frame 3 are matched and fitted with the two sides of the same plate to ensure that the plate is reliably positioned and remains parallel.

[0049] In this embodiment, the sub-board frame 4 and the main board frame 3 have the same structure, which facilitates batch processing and effectively reduces processing costs.

[0050] The other structures and effects of the mold clamping mechanism described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0051] Example 3:

[0052] Compared to Embodiment 1 or 2, this embodiment provides a blow molding machine.

[0053] A blow molding machine comprises a base on which a heating mechanism, a transfer mechanism, a blow molding mechanism, and a mold closing mechanism are mounted. The transfer mechanism receives preforms from the heating mechanism and conveys them to the mold closing mechanism, where the preforms are blown into bottles by the blow molding mechanism within the mold closing mechanism. Since the mold closing mechanism of the blow molding machine needs to work in conjunction with the blow molding mechanism, and the blow molding mechanism is positioned above the mold closing mechanism, both single-action and double-action mold platen 9 structures can be used.

[0054] The other structures and effects of the mold clamping mechanism described in this embodiment are the same as those in Embodiment 1 or 2, and will not be repeated here.

[0055] Example 4:

[0056] Compared to Embodiment 1 or 2, this embodiment provides a blow molding machine.

[0057] like Figure 6 The injection molding machine shown includes a base, on which an injection molding mechanism 15 and a mold clamping mechanism are mounted. Softened raw material in the injection molding mechanism 15 is conveyed to the mold cavity within the mold clamping mechanism and cooled and solidified. Since the mold clamping mechanism of the injection molding machine needs to work in conjunction with the injection molding mechanism 15, and the injection molding mechanism 15 is located at one end of the mold clamping mechanism, a fixed mold plate 10 needs to be installed at the end of the mold clamping mechanism closest to the injection molding mechanism 15. Therefore, a single-acting mold plate 9 structure is suitable for the mold clamping mechanism.

[0058] The other structures and effects of the mold clamping mechanism described in this embodiment are the same as those in Embodiment 1 or 2, and will not be repeated here.
